Formation of ionic polymer membrane by using banana peel. (2021) - Raturi, Poonam
Abstract: The banana is one of the healthiest fruits in the world. In India after mango, banana is the second important fruit to crop. It belongs to the Musa family in plants and grown in warmer areas. As we know it's a good source of fiber, potassium, vitamin B6, vitamin C and various antioxidants and phytonutrients. Similarly the banana peel also contains lots of nutrients like potassium, dietary fiber, polyunsaturated fats and amino acid. The aim of this paper is to utilize the waste, banana peel as biodegradable material to form an ionic polymer membrane. The conductivity to be changed when we change the quantity of banana peel (BP). For fabrication of this membrane we are using Polyvinylidene fluoride (PVDF), Polyvinyl pyrrolidone (PVP) and banana peel. Dimethalyformamide (DMF) is use as a solvent. Through impedance analyzer the capacitance, resistance, impedance and dielectric constant are measured. We are taking different banana peel solution and fabricate the ionic membrane. And finally calculate their impedance, resistance, capacitance, dielectric at different frequency. The frequency range starts from 20hz to10mhz. Between these ranges we have calculated the value more than 1600. The conductivity of PVDF/PVP/BP is enhanced from 3 × 10 -8 S to 8 × 10 -7 S by increasing the concentration of banana peel from 1 ml to 4 ml. The composition of PVDF/PVP/ 4 ml of BP shows good conduction with low dielectric constant and high dissipation factor. Through this membrane the waste, banana peel will be utilized.
